ReactJS is used to design user interfaces, also called views. One of the plus points of ReactJS is that it takes care of the view and gives absolute control of the application for you to decide.

Out of several tools and technologies available for web development, what makes ReactJS the favorite for many ❓

  • Enhanced User Experience 👥

ReactJS focuses on user experience, unlike AngularJS and other technologies. It provides users with a highly responsive interface, all thanks to JavaScript interactions between the native environment of the device and ReactJS. This makes web apps user-friendly and fast.

  • JSX 💻

JSX syntax is a blend of JavaScript and HTML. ReactJS uses JSX making it efficient and easy to code. JSX makes writing components easier, while HTML allows developers to render functions without concatenating strings.
Proper use of native APIs is the added advantage to ReactJS, while JavaScript adds cross-platform support to it.

  • High efficiency 📈

ReactJS creates its own virtual DOM where all the components live, resulting in performance gains because ReactJS presumes the changes needed in the DOM and updates the DOM trees accordingly. This way, ReactJS saves costly DOM operations and makes the pages efficient.

  • Reusable Components ♻️

ReactJS offers the ability to reuse components of different levels. ReactJS components are isolated, and changes in one do not affect others. This reuse adds up to increased efficiency in coding and thus saves time.

  • SEO Friendly 🤝🏻

For ages, JavaScript has been a no-go for search recommendations on search engines. Search engines often fail to understand JavaScript and hence degrades the SEO scores of the website. ReactJS solves this problem since it renders the page over a server, and the virtual DOM is rendered as a standard page. Search Engine Optimization is no longer a hassle with ReactJS.
